POP5 26.1
Determine the minimum height of a vertical flat mirror in which a person 5' 10" in height can see his or her full image. (A ray diagram would be helpful).
A. 2' 11"
B. 3' 9"
C. 5' 10"
D. Depends on distance to mirror.

Answer























klm
A candle is placed 8.0 cm in front of a concave mirror with a radius of curvature of 20 cm. Where is the image?
A. +20 cm
B. −40 cm
C. +2.5 cm
D. −12 cm
Answer















klm
Observer 1 sees an image of a flower at location C. At which location does observer 2 see the image of the flower?

Answer

























 



A. 2' 11"
































 



4. D
































 



ray C

As it obeys the law of reflection, ray C reflects off the vertex of the mirror as if it were a plane mirror. This is because the slope of the mirror goes to zero at the vertex.




















 




B. −40 cm





















 



Location C
The location of the image is determined by the location of the object, not the position of the observer.
